摘要:
A method for the production of a particle-containing preparation of tetrahydro-3,5-dimethyl-1,3,5-thiadiazin-2-thione, by combination of a first aqueous solution containing methylammonium-N-methyldithiocarbamate with a second solution containing formaldehyde and separation and drying of the solid formed is disclosed. The invention is characterised in that the first and second solutions are combined such that over the duration of the reaction the ratio of the concentration of dithiocarbamate functions and formaldehyde in the reaction mixture remains essentially constant over time.
摘要:
Die vorliegende Erfindung betrifft cyclische Aminale, die ausgehend von Duftstoffaldehyden oder Biozidaldehyden erhalten werden können, und sich beispielsweise zur Beduftung oder Konservierung von Wasch- und Reinigungsmitteln und der durch die Wasch- und Reinigungsmittel behandelten Materialien eignen, da sie bei der Hydrolyse die duftenden oder antimikrobiellen Aldehyde freisetzen.

摘要:
Corrosion of metallic tubulars in an oil, gas or geothermal well may be inhibited by introducing into the well a dithiazine derivative. The dithiazine may be isolated from a whole spent fluid (WSF) formed by reaction of hydrogen sulfide and a triazine. Alternately, the whole spent fluid containing dithiazine or dithiazine derivative and a corrosion inhibiting formulation may be used to inhibit corrosion in the well.
摘要:
A compound represented by the formula (I) [wherein A represents the formula CY1Y2OCY3Y4, CY1Y2SOnCY3Y4, CY1Y2NRCY3Y4, CY1=NCY3Y4, or CY1Y2N=CY3 (wherein n is 0, 1, or 2, and Y1, Y2, Y3, and Y4 each independently represents hydrogen, alkyl, or haloalkyl); R represents hydrogen, halogeno, an optionally substituted hydrocarbon group, etc.; Q1 represents substituted phenyl or a substituted aromatic heterocyclic group; and Q2 represents substituted phenyl, alkyl, or haloalkyl] or a salt of the compound; a process for producing the compound or salt; and an insecticide containing the compound or salt. Besides being applicable by spraying, the insecticide can be used for soil treatment and seed treatment.
摘要:
Described is a method of producing tetrahydro-3,5-dimethyl-1,3,5-thiadiazin-2-thion powder (I) substantially free of dust fines by reacting methylamine (II) with carbon disulphide (III) and formaldehyde (IV) or by reacting the methylammonium salt of N-methyldithiocarbamic acid (V) with formaldehyde (IV), characterized in that the reaction is carried out in the presence of at least one diaminoalkylene of the formula (VI): R -NH-A-NH-R , in which R and R , independently of each other, are hydrogen or an alkyl group and A is an optionally substituted 1,2-ethylene, 1,3-propylene or 1,4-butylene bridge.
